[Qemu-devel] [PATCH 00/39] Make configure command line autoconf-compatible

[Paolo Bonzini]

Here is the patch series implementing the idea I mentioned a while ago.

The first 14 introduce small changes to group pieces of code together
and help understanding/reviewing the next changes.  Most of them are
just cosmetic changes, though some of them have small behavioral changes.

After these come 19 patches that introduce autoconf-compatible aliases
for options not respecting the autoconf command-line syntax.  The old
versions are deprecated, but there is no change in semantics: the new
aliases take exactly the same syntax.

There are also patches also rename the "interp_prefix" and "source_path"
concepts to "sysroot" and "srcdir", which is consistent with GNU Makefile
standards and with the  with the new aliasesnew aliases.

Patches 34 to 36 introduce new command-line options for cross-compilation
that are again compatible with the GNU standards.  With these changes
it is more or less possible to drop QEMU inside a GCC/binutils tree
configured for cross-compilation and make it build together.

Patch 37 is a simple change to the help text now that the command-line
syntax is finalized.

Patch 38 and 39, finally, make a few more baby steps using host triplets
instead of custom feature detection.

Paolo Bonzini (39):
  default compilation tools to environment variables
  default make and install to environment variables
  move feature variables to the top
  fix sparse support (?)
  test cc with the complete set of chosen flags
  include failed source file in config.log
  do not pass bogus $(srcdir) include paths to cc during configure
  provide portable sizeof(long) test
  fix spelling of $pkg_config, move default together with other cross tools
  do not default to non-prefixed pkg-config when cross compiling
  reorganize sdl-config tests
  move --srcdir detection earlier
  properly detect compiler in tests/Makefile
  remove HOST_CC mention from roms/{sea,vga}bios/config.mak
  let --host-cc slide into oblivion
  introduce CFLAGS= and LDFLAGS= configure command-line options
  introduce CPPFLAGS configure variable
  add autoconfy alias CC= for --cc
  add CPP variable
  add autoconfy aliases MAKE=/INSTALL= for --make and --install
  add autoconfy aliases --with-* for audio library options
  make trace options use autoconfy names
  deprecate --audio-card-list
  add autoconfy alias --enable-audio-drivers alias for --audio-drv-list
  add autoconfy alias --enable-block-drivers for --block-drv-whitelist
  add libtooly alias --enable-static for --static
  add autoconfy alias --with-sysroot for --interp-prefix
  rename interp_prefix to sysroot
  add autoconfy alias --enable-targets for --target-list
  add autoconfy alias --with-headers for --kerneldir
  add autoconfy alias --srcdir= for --source-path
  rename SRC_PATH to srcdir
  rename source_path to srcdir
  add autoconfy --host= option deprecating --cross-prefix
  add autoconfy --build= option to be used instead of undocumented --cpu
  add autoconfy --with-arch= option, compatible with --sparc-cpu
  make more options "standard"
  provide a more gnuish default sysroot
  use host triplets for feature detection
